Diego Pasini and Contrary
In 2024, Pasini became associated with Contrary’s fellowship program. Contrary described him as a University of Pennsylvania student interested in robotics, hard technology and startup opportunities. The fellowship gave him exposure to a network focused on emerging technology and young builders.
This stage of his career was important because it placed Pasini among other young technology-focused individuals exploring entrepreneurship and advanced engineering. Rather than following a conventional corporate career path, he was developing experience through education, technical projects, venture networks and practical experimentation.
The xAI Hackathon
A major turning point in Pasini’s career came through an xAI hackathon in San Francisco. Pasini and his teammates won the event’s grand prize with an AI-related project. His LinkedIn activity confirms his participation in the winning team alongside Alex Chen and Alex Vesel.
The hackathon achievement helped establish a direct connection between Pasini and xAI. Reports subsequently stated that he joined the company in January 2025. The transition from university technology projects to a position at one of the world’s closely watched AI companies became the defining step in his early career.
Career at xAI
Pasini’s time at xAI quickly became the most prominent part of his professional biography. In 2025, reports identified him as a leader of the company’s data-annotation team, an operation involved in preparing and organizing information used to train Grok. The position placed him in charge of both contract and full-time personnel involved in the training process.
His promotion attracted attention because he was only around 20 at the time and had completed high school just two years earlier. The appointment occurred during a major restructuring at xAI, making his new responsibilities particularly significant. His rapid rise became a widely discussed example of how quickly young technical talent can advance inside the AI industry.
Diego Pasini and Grok
Grok is xAI’s flagship artificial intelligence chatbot, and the quality of its training depends heavily on data, evaluation and human feedback processes. Pasini’s 2025 role connected him directly with this important part of the AI development pipeline.
His position was especially notable because data annotation and human evaluation can influence how AI models understand information, respond to users and perform across different tasks. By taking responsibility for a major training-related team, Pasini moved beyond purely academic work into a high-profile operational role within the AI industry.
Career Change in 2026
Pasini’s role at xAI changed in 2026. Bloomberg reported in June 2026 that Jack Garabedian, an engineer from SpaceX’s Starlink operation, took over the team responsible for human data used to train Grok, replacing Pasini in that specific leadership position. Bloomberg reported that Pasini had been at xAI for about a year and a half at that point.
This development is important when describing Pasini’s career today. His earlier position as the head of the Grok training/data team should not be presented as his current title without qualification. His own website continues to state that he is at xAI, while his LinkedIn profile also lists xAI as his professional affiliation.
